To solve the expression (٨-)+٥-٦+٩-?, we can follow the order of operations. The order of operations is a set of rules that dictate the order in which operations should be performed in a mathematical expression. The order of operations is as follows:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Using the order of operations, we can solve the expression as follows:
(٨-)+٥-٦+٩-? = (0)+٥-٦+٩-? = 5-٦+٩-? = -1+٩-? = 8-? = 8-2 = 6
Therefore, the answer to the expression (٨-)+٥-٦+٩-? is 6.
